So, is the higher resolution worth it in such a small screen? If this was a PC, I would go easily with the higher spec, but I know that higher screen settings require more power - easily covered by a PC.

Given limited power in these units, could that make the 800x480 faster ...and still give great IQ ..say for jpegs?

Thanks for ANY & ALL help ..want to make the best decision I can ..so don't be shy.
